Hi. I'm really hoping someone can help with this. I've got a Mini Convertible and when the stereo died I replaced it with one that has an aux in thinking I'd be able to utilise it for playing tunes from a device. I'm not an iPhone or iPod owner so ideally I'd like to use my HTC One. So I got myself a nice cable to go from the headphone jack on the phone to the aux in. Turned Blinkbox music app on and - nothing. Now it appeared there were two good signs. 1. That the phone recognised them as 'headphones' as the relevant icon appeared at the top of the phone screen and 2. If I'm not mistaken the stereo seemed to be processing music because the graphic equalise type bars were visible and going up and down as though sound was going through the stereo. Just there was absolutely no sound coming out the car's speakers. Do I need to do something to the phone, get an app, put the music on an SD card, what's not working?? Also, is it likely/impossible that I could (if I can get it working) both listen to music and have my GPS on at the same time?
